SPECIFIGATION forming part of Letters Patent No. 707,973, dated August 26, 1902.

Application filed May 29.1902. Serial. No. 109,431. on model.)

To alt whom it may concern:

Be it known that I, THEODOR H. J. Lncx- BAND, a citizen of the United States, residing at Adair, in the county of Adair and State of Iowa, have invented a new and useful Carburetor, of which the following is a specification.

My object is to provide a simple means of. regulating the qualityof gas produced in a carburetor; and my-jinvention consists -iu' a 1o plurality of air-distributors andmoans for.

jointly raising and loweringthem when im-. mersed in oil in a tank,as hereinafter set forth, pointed out in my"claims,and illustrated in the accompanying drawings, in which- Figure 1 is a vertical central sectional View of my improved carburetor, that shows the. airdistributors adj ustably' connected with fixed air-distributing tubes and mechanism for raising and lowering the air-distributors. Fig. 2 is a view on the line a: wof Fig.'11ooking downward upon the'air-distributers.

The letter A designates an air-tight tank, that may vary in size as'dosired. An air conveying tube B is fixed in the top portion 2 5 in a horizontal position and a plurality of airdistributing tubes O are fixed-to the tube B to extend down near the bottom of the tank and are open at their free ends fordischarg ing air into oil in the tank. 7

To each tube 0 is slidingly connected an elongated air-distributerD,thatis cone-shaped in cross-section, as shown in Fig. 1, and extends across the inside of the tank, as shown in Fig. 2. The forms of the two parallel con- 3 5 tral ones and those at their sides differ .in shape, as .shown and as required to jointly fill the circular interior space of the tank. They are perforated to allow air to filter from their insides outward to ascend through oil 0 upward, as required to volatilize the oil and mingle air andoil-to. produce gas. Sleeves or tubular extensions f at their tops and centers serveas guides on the tubes 0 to retain the distributors D in proper positions as they are raised and lowered. They, are also. rig-.

idly connected by metal straps g and g, fixed across their tops in parallel position, as shown in Fig. 2. A second series of distributors H are fixed on top of the metal straps by means of a cross-bar k, fixed thereto, and a metal strap 7s, fixed across their tops, as shown in Fig. 1, or in any suitable way, so all the distributors D and H can be jointly adjusted relative to the bottomof the tank and oil therein. A lever L is connected to the top of the tank by means of a pivoted fulcrum m and a rod 01', detachably fixed to the metal cross-bar I a and'tlie metal strap-k, as shown in Fig. 1, and

extended up' through a stuffing-box n, fixed in the top and center of the tank and pivotally. connoctedwith the lever L in such a manner that all the distributors can be jointly raised and lowered by means of the lever and retained at any pointof elevation by means ofa rack r, fixed on top of the tank to engage the lever,'as shownin Fig. 1, or in any suitableway.

In the practical operation of my invention "air is discharged from the lower open ends of the tubes 0 and bubbles up in the oil into the distributors and passes through their perforations and isthus divided minutely in the oil before it rises above the oil, as required to volatilize the oil to produce gas. It is obvious the quality of the gas depends upon the amount of oil or hydrocarbon that is mixed with the air, and it is. also obvious that the quantity ofoil thus vaporized and mingled with the air can be readily governed by raising and lowering the distributors D, as requirod, to utilize onlythe lower series D and only portions 'of them when it is desired to reduce the richness of the gas or to use all of the distributors D and parts or all of the upper seri'os H. for increasing the, richness. A simple means of regulating the quality of the gas is thus provided that can be readily and advantageously operated for making gas of the right quality for practical use.

Having thus described the purpose, constru'ction, and operation of my invention, its practical utility will be readily understood by persons familiar with the art to which it pertains, and

What I claim as new, and desire to secure 5 by Letters Patent, is

1. In a carburetor for gas-machines, an'airtight tank, a fixed tube extending horizontally in the top portion of the tank, a plurality of tubes fixed to the horizontal tube to exwe tend into the lower portion of the tank, elongated air-distributors fixed together and slidingly connected with the lower ends of the fixed tubes, means for raising and lowering the air-distributers and means for retaining them stationary at different points of elevation, arranged and combined to operate in the manner set forth for the purposes stated.

2. In a carburetor for gas-machines, an airtight tank, a tube fixed in the top portion of the tank to extend horizontally, a plurality of tubes extending vertically and fixed to the horizontal tube, an air-distributor slidably connected with each fixed upright tube, means for jointly raising and lowering the distributers relative to the bottom of the tank and a plurality of air-distributers fixed on top of the distributers slidably connected with the upright tubes, to operate in the manner set forth for the purposes stated.

a rack for retaining the lever in a fixed posi- L tion, arranged and combined to operate in the manner set forth for the purposes stated.
